FODDER FOR HORSES AND OTHER ANTMlAlLS.

Patented Dec. 29, 1908.

To all whom it may concern: 9

Be it known that I, BERTHOLD STEIN, a subject of Germany, and a resident of New York city, in the county of ,New York and State of New York, have invented certain new and useful Improvements in Fodder for Horses and other Animals, ofwhich the following is a specification.

The invention relates to a new food or fodder'for horses and other animals.

It is well known that brewers grains, regarded as a waste product of breweries, are. fed to horses and cattle, and it is generally well understood that these grains having been deprived of a substantial portion of their food value do not afford sufficient nutriment and strength-giving qualities to enable animals fed on them to do hard work or withstand continued strains.

The object of this invention is with the use of a further-waste product of breweries, to render the grain-fodder palatable, easilydigested and very nutritious, the fodder of my invention possessing all elements necessary for the maintaining and building-up of the systems of herbivorous animals.

My invention contemplates. the use of brewers grains, with additional ingredients, to-wit: peptone, phosphates and fats made or recovered from the yeast of breweries. While some uses for this yeast have heretofore been proposed, it is well-known that thousands of pounds of it daily go to waste. My purpose is to utilize this yeast and add certain products derived from it to the grains, and thus not only avoid the great waste of yeast but render the grains not only suitable for but highly efficacious as fodder. The yeast of breweries contains. about fifty per cent of albumen, but, in its natural condition, it is useless as fodder owing to its bitterness, due to the presence of hop-rosin and the lupulin contained therein.

The hop-rosin and lupulin would prove to be detrimental to the well-being of horses and cattle if fed to them, and, further, should the yeast be fed to horses or other animals in its natural state, the fermentation would continue an cause serious stomach derangements a (l'iDdIgGStIOII.

In accordance with my invention," I- sub ject the yeast to a process for the production or recover phates an fats, and m. carrying out' this therefrom of peptone, phosgrains or brewe treatment I boil the yeast in the presence of water under pressure. The albumen of the yeast is by this boiling altered into peptone,

soluble in water. The boiling is continued about three hours, and then the mixture is allowed to stand for a suitable period to cool and settle, after which the supernatant .liquid'which contains the peptone in soludiscarded. The dried peptone, phosphates and fats thus produced or recovered from the yeast are then, in powdered form; mixed with the dried brewers grains, preferably with the additionof a suitable quantity of molasses, sirup or the like. 7

The fodder so manufactured represents a dry, loose substance, staple and unchanging under normal conditions, palatable, easily digested and very-nutritious, differing greatly fromafodder c nsisting sim ly of brewers in grains 11K yeast.

The fodder of my invention is not only new and highly eflicient in food value but 1s reduced mainly from the waste products of Breweries and in its manufacture enables the use with greatadvantage of the yeast which while containing valuable ingredients has heretofore in enormous quantities been.

wasted.

I deem itvery much better to recover the peptone, hosphates and fats from the yeast and add all wish to'limit my invention exclusively to the use in the fodder of the phosphates and fats, since the addition of said peptone alone to the brewers grains will produce a vegetable pe tone fodder of very desirable character. hat I claim as my invention and' desire to secure by Letters Patent, is:

1. A vegetable'fodder comprising dried brewers rains and dry powdered peptone derived rom brewers yeast and separated from the hop-rosin and In ulin of the yeast, the whole bein thorough y mixed.

'2. A vegeta le fodder comprising dried brewers grains, dry powdered peptone deof them to the grains, but I do not
